Appendix C] OF THE PAMIRS AND OXUS BASIN 1007
show io per cent. of the Özbeg as fair-haired. This is probably an entirely false proportion, due to random sampling, which would be corrected if data could be obtained from a greater number of individuals. Nevertheless, these characters are often of considerable value as indicating certain definite tendencies.
Skin-colour.—I have already dealt with skin-colour, and will merely recapitulate. All peoples show ioo per cent. of ` white-rosy complexions save for the following exceptions :
Kirghiz . 7 per cent. brownish-white.
Sistani . 64 „ „ „
Sayad . 71
Biloch . 86
The measurements have shown that no connexion can be found between the Kirghiz and the others ; consequently the tendency to pigmentation on the part of the Kirghiz, which, after all, is comparatively slight, must be due to another cause. Referring to the Kirghiz measured on the previous expedition, we find that the tendency is far stronger, and is shared to some extent by members of the Taklamakan desert population, who are also broad-nosed. This tendency to pigmentation, therefore, is probably natural to the broad-nosed variety of MongoloTurki peoples, and has been acquired from them, though in lesser degree, by the desert population.
The Sistani-Sayad-Biloch combination, however, show a far higher percentage, which is probably due to a strong Indo-Persian or Indo-Afghan strain.
Eye-colour.—Three categories : dark, medium, and light (including blue). The tribes of which the bulk of the population may be classed as dark-eyed are the following :
None of these include a single light-eyed individual. The eye-colour, therefore, of the Biloch-Sistani-Sayad combination agrees with the skin-colour. To continue :
Roshani . 6i
Darwazi . 6o
Both of these tribes include light-eyed individuals, and it is necessary to consider the percentages of the ` medium' and ` light ' categories before deciding on the relative position of the two. The figures are :
Per cent. Per cent.
Roshani 25 14
Darwazi 32 8
It is clear that the Darwazi are, on the whole, more consistently dark-eyed than the Roshani.
That concludes the series of peoples of whom more than 5o per cent. of individuals are definitely dark-eyed. It includes the whole of the Sistani-Sayad-Biloch group ; the Özbeg ; two of the Wanji-Darwazi-KarateginYazgulami group ; and one of the Roshani-Shughnani-Ishkashmi-Wakhi group—the high percentage of dark eyes among the Roshani being rather countered by a percentage of light-eyed individuals which, as will appear later, is relatively very high.
If we take the next highest percentage of dark eyes, we have :
Karategin . 44
Kirghiz . 41
Yazgulami . 40
